Bug 43094

While trying to play the game Ryzom with latest mesa compiled from git the program terminates with error "ir_swizzle @ 0xe134ae0 specifies a channel not present in the value".

Switching back to the stable branch mesa-7.11 (haven´t tried mesa-7.11.1) the error is gone.

My glxinfo:

OpenGL renderer string: Gallium 0.4 on AMD BARTS
OpenGL version string: 2.1 Mesa 7.12-devel (git-ec174a4)
OpenGL shading language version string: 1.20


Here is the backtrace:

Core was generated by `/usr/games/ryzom_client'.

Let me know if you need anything further to track down the error.
